Hello everyone, I've been building 3D printers for a long time now and I thought I might be able to help some of you out. I don't know everything of 3D printing and I like many of you, learn something new everyday. I will be helping to Moderate the site as well as help out wherever I can. I definitely can say that I specialize in Printrbot line-up but, I have designed and built many of my own RepRaps. So if you have any questions or need any help, I will do the best I can to get you printing.
